When paper is used as a recording medium for information, recorded information can be listed. Information can be viewed side by side. There are advantages such as a high degree of freedom in places to watch.
However, since it takes time to rewrite the information, the paper on which the information is already written at the time of updating the information is thrown away. As a result, there is a problem in that the environmental load such as depletion of resources such as wood, which is a raw material of paper, and emission of carbon dioxide is increased.

As information display means for displaying information such as images and characters, for example, a CRT display, a liquid crystal display and the like can be mentioned. These displays have the advantage that the displayed information can be easily rewritten or erased and the information can be rewritten many times. However, the CRT has a problem that the eyes are easily tired, and the liquid crystal display has a problem that the resolution is not sufficient as compared with the resolution at the time of recording information on paper.

Therefore, a recording medium, such as a display, which can rewrite image information many times while maintaining the convenience of paper is expected. As one of image recording apparatuses using a recording medium on which image information can be rewritten, there is, for example, an apparatus disclosed in Japanese Patent Laid-Open No. 6-67141.

A recording medium sheet provided with a protective film is used. That is, in the above-described image recording apparatus, the arrangement state of the liquid crystal is changed by the electric field applied to the recording medium sheet to write and erase information.

Here, a process of writing and erasing information in the image recording apparatus will be described below with reference to FIG.

First, the recording medium sheet 501 passes between the two rolls 512a and 512b to which the initialization power source is connected, thereby generating a high-frequency voltage or a charge for writing image information on the recording medium sheet 501 or The information is erased and initialized by applying a charge or a voltage having a polarity opposite to the polarity of the voltage.

After that, the surface of the organic photoconductor 503 charged to a negative charge by the corona charger 505 is irradiated with light of a pattern corresponding to characters and image information by the exposure unit 504, and the surface of the organic photoconductor 503 is exposed. The information is written by passing the recording medium sheet 501 between the drum 502 on which the charge pattern corresponding to the recording medium is formed and the transfer roller 506, and applying a charge or voltage pattern to the recording medium sheet 501.

Then, in order to prevent electric shock, the recording medium sheet 501 on which information has been written is passed between the two rolls 508a and 508b for discharging to remove the electric charge. Is discharged.

The recording medium sheet 501 has a thickness of 0.1
mm, and is formed in a film shape. Information such as characters and images can be rewritten / erased any number of times.
Since the light modulation member constituting 01 has a memory property,
The written information can be held for a long time.

It is configured to be openable and closable with AA ′ as a fulcrum. That is, the pressing member 53 is opened when the liquid crystal paper 11 is removed, and closed when the liquid crystal paper 11 is attached, so that the liquid crystal paper 11 is pressed against the cylindrical member 51.

As described above, the mechanism (winding means) for securely winding the liquid crystal paper around the cylindrical member is shown in FIG.
(A) A cylindrical member 61 as shown in (b) may be used.

The cylindrical member 61 is provided with a circular guide member 62 whose longitudinal direction is wider than the width of the liquid crystal paper 11 and whose both ends are larger than the diameter of the cylindrical member 61. As a result, a concave portion 65 having at least the width of the liquid crystal paper 11 is provided at the center of the cylindrical member 61.

Further, at least one protrusion 63 is formed on a part of the surface of the recess 65. As shown in FIG. 8B, the liquid crystal paper 11 used at this time is provided with an opening 22 b in the non-information display area 22 to be fitted with the projection 63 of the cylindrical member 61.

They are formed to have the same shape. In this case, the identification symbols 81 and 82 include three bars arranged at equal intervals,
The bar code is composed of a single bar slightly larger than these bars.

As the identification signal detecting means 76 for detecting the identification symbols 81 and 82, for example, a detecting means such as a photo interrupter is used. When this photo interrupter is used, the pattern identification symbols 81 and 82 shown in FIG.
The identification signals A and B as shown in FIG. In other words, when the liquid crystal paper 11 is conveyed in the direction of arrow P, the identification symbol 81 is first detected, and FIG.
An identification signal A as shown in FIG. Thereafter, what is detected is the identification symbol 82, and an identification signal B as shown in FIG. 20B is obtained. When the identification signals A and B are input to the control unit 80, the drive control of the drive unit 41 is performed.

When transporting the liquid crystal paper 11 in the direction of arrow P from the state shown in FIG. 19, ie, when erasing the information written on the liquid crystal paper 11, first, the identification symbol 81 is detected inside the apparatus main body 31. After that, the identification symbol 82 is detected. That is, the identification code 8
When 1 is detected, an identification signal A as shown in FIG. This identification signal A is
The control unit 80 does not stop the driving of the driving unit 41 because the signal indicates that the front end of the liquid crystal paper 11 has been detected. Thereafter, when the identification symbol 82 is detected, the identification signal B as shown in FIG. Since the identification signal B is a signal indicating that the rear end of the liquid crystal paper 11 has been detected, the control means 8
0 stops the driving means 41 after a predetermined time (t = n).

That is, after the first identification code 81 is detected by the identification signal detecting means 76, when the middle of the liquid crystal paper 11 approaches the identification signal detecting means 76, the transport of the liquid crystal paper 11 is not stopped. However, when the end portion approaches, after the identification symbol 82 is detected, the conveyance of the liquid crystal paper 11 is stopped after a predetermined time has elapsed. At this time,
When the transport of the liquid crystal paper 11 is stopped at an arbitrary position, it is set so that it cannot be stopped at the position corresponding to the identification symbol 82.

In the same manner, the liquid crystal paper 11 is
The same control as described above may be performed when pulling out the liquid crystal paper 11 stored in the apparatus main body 31 when pulling out the liquid crystal paper 11 stored in the apparatus main body 31 from the state stored in the apparatus main body 31. In this case, the identification symbol 82 is first detected by the identification signal detection means 76, and the identification signal A shown in FIG. 20A is obtained. Thereafter, the identification signal detecting means 76
As a result, the identification symbol 81 is detected, and an identification signal B as shown in FIG. Then, this identification signal B
After a predetermined time (t = m) has passed since the time when
The transportation of the liquid crystal paper 11 may be stopped.

Here, the flow of the transport control of the liquid crystal paper 11 based on the detection of the identification symbol will be described below with reference to the flowchart shown in FIG. In the information recording apparatus, the time when the liquid crystal paper 11 is carried out of the apparatus main body 31 is referred to as information writing, and the time when the liquid crystal paper 11 is stored in the apparatus main body 31 is referred to as information erasing. The transport control of the liquid crystal paper 11 at the time of writing and erasing is basically the same.
Description will be made with reference to the same flowchart.

First, the control means 80 detects an identification signal for the liquid crystal paper 11 being conveyed (S
1) It is determined whether the detected identification signal is a B type (identification signal B) (S2). That is, FIG.
It is determined whether or not the identification signal B shown in FIG.

In S2, if the identification signal B is not detected, the flow shifts to S1, and the identification signal is detected again.

On the other hand, if the identification signal B is detected in S2, the driving means is stopped after m seconds or n seconds (S3).

Here, m seconds is a time previously set in a timer t1 built in the apparatus main body 31 at the time of recording. That is, the drive unit 41 is stopped m seconds after the detection of the identification signal B. In this case, the liquid crystal paper 11 is carried out of the apparatus main body 31, predetermined information is written in the information display area 21 of the liquid crystal paper 11, and the liquid crystal paper 11 is stopped in a state where the entire surface is displayed.

[0199] Further, n seconds is a time previously set in a timer t1 built in the apparatus main body 31 at the time of erasing. That is, the drive unit 41 is stopped n seconds after the identification signal B is detected. In this case, the liquid crystal paper 11 is stored in the apparatus main body 31, all the information of the liquid crystal paper is erased, and the liquid crystal paper 11 is stopped in a state where the information display area 21 is located in front of the information recording means 40 (on the sheet storage section 33 side). I have.

It is also possible to form a second identification symbol outside the identification symbols 81 and 82 in which the pattern interval changes toward the front end and the rear end of the liquid crystal paper 11. For example, as shown in FIG. 22, an identification symbol 8 in which the interval of the pattern is shortened toward the front end and the rear end.
1 'and 82' are provided outside the identification symbols 81 and 82 shown in FIG.

When the above-described identification symbols 81 'and 82' are detected by the identification signal detecting means 76, the signals shown in FIG.
The identification signals C and D as shown in FIG. In this case, the control means 80 does not stop the transport of the liquid crystal paper 11 when the identification signal C is detected, but immediately stops the driving means 41 when the identification signal D is detected, and stops the transport of the liquid crystal paper 11.

Therefore, when the transport of the liquid crystal paper 11 has already been stopped by the identification signal B and re-transport is performed due to an erroneous operation, the signal is read for a certain period of time by detecting the identification signal D. Thereafter, the transport of the liquid crystal paper 11 is stopped, and the liquid crystal paper 11 is transported in the reverse direction for the time when the signal is read, so as to return to the original stop position.

As described above, by providing the identification symbols 81 'and 82' outside the identification symbols 81 and 82, it is possible to prevent the liquid crystal paper 11 from being excessively carried out or stored in a state where the liquid crystal paper 11 is carried out or stored. can do.

The above-described method for preventing erroneous operation will be described below with reference to the flowchart shown in FIG. In this description, it is assumed that the liquid crystal paper 11 stopped by the identification signal B is transported again due to an erroneous operation.

First, the second identification signal is detected (S1).
1). Here, the identification code 81 'or the identification code 8
The detection of the identification signal C or the identification signal D obtained from any of 2 ′ is performed.

Next, it is determined whether or not the detected second identification signal is a D type (identification signal D) (S12). here,
If it is determined that the identification signal D has not been detected, S11
And the detection of the second identification signal is performed again.

On the other hand, if it is determined in S12 that the identification signal D has been detected, the driving means 41 is immediately stopped, the fact that driving is impossible is displayed on the display unit 34, and an alarm is issued (S13).

FIG. 2 shows another method for preventing erroneous operation.
This will be described below with reference to the flowchart shown in FIG.

First, an identification signal obtained from the identification symbol is detected (S21).

Next, it is determined whether or not the identification signal obtained from the identification symbol is of the B type (identification signal B) shown in FIG. 20B (S22).

Here, if it is determined that the identification signal B has not been detected, the flow shifts to S21, where the identification signal is detected again.

On the other hand, if it is determined in S22 that the identification signal B has been detected, the driving means 41 is stopped after m seconds or n seconds (S23).

Here, m seconds is a time previously set in a timer t1 built in the apparatus main body 31 at the time of recording. That is, the drive unit 41 is stopped m seconds after the detection of the identification signal B. In this case, the liquid crystal paper 11 is carried out of the apparatus main body 31, predetermined information is written in the information display area 21 of the liquid crystal paper 11, and the liquid crystal paper 11 is stopped in a state where the entire surface is displayed.

Further, n seconds is a time previously set in a timer t1 built in the apparatus main body 31 at the time of erasing. That is, the drive unit 41 is stopped n seconds after the identification signal B is detected. In this case, the liquid crystal paper 11 is stored in the apparatus main body 31, all the information on the liquid crystal paper 11 is erased, and the liquid crystal paper 11 stops in a state where the information display area 21 is located in front of the information recording means 40 (on the sheet storage section 33 side). ing.

After the driving means 41 stops, the rotation direction of the driving means 41 is switched to the opposite direction (S2).
4).

As described above, the identification symbols 81, 82, 81 ', 82' provided on the liquid crystal paper 11 are recognized, and the identification signal (A) obtained from these identification symbols 81, 82, 81 ', 82' is obtained. , B, C, and D), and if the identification signal is a signal indicating the rear end portion of the transport, the excessive transport of the liquid crystal paper 11 can be reliably prevented by switching the rotation direction of the driving unit 41. .

The size of the identification symbols 81 and 82 is set to be sufficiently larger than the size of the identification symbol detecting section of the identification signal detecting means 76. When a photo interrupter is used for the identification signal detecting means 76, the size (slit width) of the light receiving portion of the photo interrupter is about 1 mm at most, and the size of the identification symbol may be set to 1 mm or more.

That is, as shown in FIG. 26, the length W of the identification symbol 82 provided on the non-information display area 22 of the liquid crystal paper 11 is determined by the light receiving portion 76a of the identification signal detecting means 76.
May be set so as to be sufficiently larger than the width w.

By setting as described above, the identification symbol can be recognized with certainty even if the transport of the liquid crystal paper 11 is uneven or the identification symbol is slightly displaced.

[0220] In the above example, as shown in Fig. 19, only one identification symbol 81 or 82 is provided on the same side. However, the present invention is not limited to this.
As described above, a plurality of identification symbols may be provided on the same side depending on the purpose of use.
